' INTERNAL-COMBUSTION Emerita."

Application filed August 31, 1925. Serial imasaesa This invention relates to the lubrication of internal combustion engines and more particularly to the splash pans therefor.

In those internalcombustion englnes employing'pressure lubrication the oil is circulated by means of apump'which draws it w it increases wear.

up through a pipe out of a reservoir and: forces itthrough distributing PlPeS'liO the bearings and variousother working parts.

7 After being used in these parts, the oil then falls or'drips down to the splash pan and is directed into a strainer throughan opening in the splash pan where the sediment is removed and then flows into the reservoir where it-is again-picked up bythe pump and distributed. a

Considerable dirt and grit aredrawn into the crankcase through the breather tube and 1 also some sediment, such 'as steel dust and 20 the like'from the friction surfaces, is picked up by the oil as it is circulated. Much of this sediment is too small to be removed by the strainer screen and continually flows around With the oil to the bearings where many cases do not change it for months at a time. It is especially in these cars that the sediment gust mentioned accumulates and doesserious damage to the working parts of the engine, and it is tosafeguard these people as well as to prevent wear to the ordinary enginethat present inven-;

tion has been provided.

\Vith the above in view, it is the primary object of the present invention to provide a new and novel means for collecting the sediment from the-oil used in an internal Another object is to provide splash pan for an internal combustion engine with means for collecting fine sediment from the, lubricating oil, which means is simple in con-V struction easy .to assemble and is economical to manufacture. '7 I V A further object is to provide an oil splash to likecparts:- a I F gurel s a partial transversesectional Some of it even works ofthe 'oil pan 11, through a pipe forced by a pump or some'su'ch device (not shown) through distributing lines to the pan for an internal combustionengine with 1 a layer of felt or similarmaterialfover the entire surface thereof, 'toremove finesedi over and through the same.

ment from the lubricating oil as it flows These being among the. objects of the;

present invention; the same consists of oer-V V tain features of construction and oCflmbinations of partsL-to be hereinafterdescribed with reference to the accompanying cl'iawrng, and then cla med, hav ng theabove and;

other objects-inview. o I

In the accompanying drawing which illustrates asuitable embodiment of the present invention and n wh ch like-numerals refer View of an internalcombustion engine having an oilpan and a splaslrpan embodying the construction of the present invention. I Figure 2 is a brokenv perspective view of the splashpan shown in Figure 1 illustrating the device of the present invention assembled thereon.

The oil in making its circuit is drawn from the reservoir 10 formed by the walls 12 and is bearings 13 for the crankshaft 14, the bearings '15 for the connecting rods 16, and to the bearings. 17 for-the cam shaft 18. Here it falls down to the splash pan l9 and flows toward and through an aperture 20 into a strainer 21, where the "heavier sediment particles are trapped and precipitated down into the removable sediment pocket 22, The Oll then passes out into the reservoir 10 carrying with it the finer sediment particles which are too small to be removed by the strainer 21 and flow with the oil to the bearings 18, 15 and 17 andother working parts.

To trap these fine sediment particles and also some of the larger ones before they reach the strainer '21, the'splash pans 19 is provided with a covering 24 on its entire surface with the exceptionof the aperture 20 and opening 23 through which'th'e pipe 12 extends, or felt or similar material having a texture of loosely associated fibers, Now

as the oil flows, from the bearings 13, 15 and 17 on to the splash pan 19-and flow toward the aperture 20, it will'tend to seep through the covering 2 1 and leave the sediment particles can ht in the fibers or filaments or the felt. mall apertures such as 25 may be provided in the bottom of the splash pan to cause the oil to seep through the felt covering 24k faster and to drain into the reservoir 20. Although the openings 25 are preferable, the bottom of the splash pan 19 may be formed with a plurality of corrugations leading to the aperture 20.

The covering 24 is preferably held in position in the splash pan 19 by a plurality of split rivets 26 which can be removed when theengine is torn down for repairs, so that the. covering 22% can be taken out and a new, clean one inserted in its place.

' From the foregoing description it can be seen that in employing theuse of a felt covering for an engine splash pan fine sediment particles andmany larger particles will be caught therein and be prevented from circulating with the lubricating oil into the many Working parts of the'engine, thereby preventing the same from increasing 'wear and from clogging the various pipe lines.

It can also be'seen that such a device is 7 easy to assemble and would be very economical to manufacture and use.

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit and sub-- stance of the broad invention, the scope of which is commensurate with the appended claims. 7

lVhat I claim is v 1. The combination with an internal com- V 2. In a lubricating system for an internal combustion engine, an oil splash pan covered with a relatively thick layer of looselyv associated fibrous material to collect foreign particles in said oil. v

3. In an internal combustion engine lubrieating system ha ing an oil pan and apar tition dividing said oil pan into an oil reservoir portion and a crankcaseportion, a layer of fibrous materialpositioned on the upper surface ot'sai'd partition'to intercept the oil flowing from said. partition into said reservoir to collect foreign particles in said oil.

4. In an internal combustion engine lubri eating system h'aving"an oil reservoir, a cover therefor having a bottom wall and side and end walls, and a layer of fibrous material covering said bottom wall and extending upwardly along said'side and end walls to collect foreign particles in the oil flowing over said cover. 7 i
